“…Similarly, all blend ratios of CME fuel showed higher BTE than standard diesel fuel. This improving trend may be due to the richer fuel-bound oxygen molecules in all methyl ester fuel blends, which enhance the combustion efficiency and this results in higher BTE [36]. This result is in agreement with results from research conducted by Man et al on blends of used palm cooking oil biodiesel.…”

Biodiesels from coconut and palm cooking oil are viable alternatives to diesel fuel due to their environmental sustainability and similar physicochemical properties compared to diesel. In the present study, these fuels were tested separately in a diesel engine by blending with fossil diesel in proportions of 10%, 20%, 30% and 40% by volume. Experiments were conducted under a constant brake mean effective pressure (BMEP) of 400 kPa and at 2000 rpm. The results revealed similarities in engine performance, emissions, combustion and engine block vibration for used palm cooking oil methyl ester (UPME) fuel blends and coconut methyl ester (CME) fuel blends. Most blends resulted in slight improvements in brake specific energy consumption (BSEC) and brake thermal efficiency (BTE). A maximum reduction of 54%, 89% and 16.8% in pollutant emissions of brake specific hydrocarbons (BSHC), brake specific carbon monoxide (BSCO) and brake specific nitrogen oxides (BSNOx), respectively, was observed with UPME and CME in the blends. The cylinder pressure profiles when UPME-diesel and CME-diesel blends were used were comparable to a standard diesel pressure trace, however, some deviations in peak pressure were also noticed. It was also apparent from the results that engine vibration was influenced by the type of methyl ester used and its blend composition. Notably, the rate of pressure increase was maintained within an acceptable limit when the engine was fueled with both of the methyl ester blends.

“…One of the properties that affect BSFC is cetane number. Increase in cetane number results in a reduction of ignition delay time, which in turn improves combustion and reduces fuel consumption [29]. All of the essential oils are inferior when compared to diesel for cetane value; hence, when essential oils are added to diesel, cetane value is reduced (as compared to base diesel) and BSFC increases [30].…”

Essential oils are derived from not-fatty parts of plants and are mostly used in aromatherapy, as well as cosmetics and perfume production. The essential oils market is growing rapidly due to their claimed health benefits. However, because only therapeutic grade oil is required in the medicinal sector, there is a substantial low-value waste stream of essential oils that can be used in the transportation and agricultural sectors. This study investigated the influence of orange, eucalyptus, and tea tree oil on engine performance and combustion characteristics of a multi-cylinder compression ignition engine. Orange, eucalyptus, and tea tree oil were blended with diesel at 10% by volume. For benchmarking, neat diesel and 10% waste cooking biodiesel-diesel blend were also tested. The selected fuels were used to conduct engine test runs with a constant engine speed (1500 RPM (revolutions per minute)) at four loads. As the load increased, frictional power losses decreased for all of the fuel samples and thus mechanical efficiency increased. At higher loads (75% and 100%), only orange oil-diesel blends produced comparable power to diesel and waste cooking biodiesel-diesel blends. Fuel consumption (brake and indicated) for the essential oil-diesel blends was higher when compared to base diesel and waste cooking biodiesel-diesel blends. Thermal efficiency for the essential oil-diesel blends was comparable to base diesel and waste cooking biodiesel-diesel blends. At higher loads, blow-by was lower for essential oil blends as compared to base diesel and waste cooking biodiesel-diesel blends. At 50% and 100% load, peak pressure was lower for all of the essential oil-diesel blends when compared to base diesel and waste cooking biodiesel-diesel blends. From the heat release rate curve, the essential oil-diesel blends ignition delay times were longer because the oils have lower cetane values. Overall, the low-value streams of these essential oils were found to be suitable for use in diesel engines at 10% blends by agricultural producers of these oils.

“…Mayank et al (2016) found that the fatty acid content in crude rice bran oil is elevated with respect to oil quality since of over fatty content. The two-step transesterification process is followed which includes acid-catalyzed transesterification and base-catalyzed transesterification [8]. Baharak et al (2016) found that the edible oil has various drawbacks like deforestation, increased vegetable oil price, to overcome which extraction can be done with nonedible oils(rice bran oil, rubber seed, mahua seed, silk cotton, babassu tree) [9].…”

Our research work mainly focusses on the examination of properties, both physical and chemical, of biodiesel blends among neat diesel at different volumetric proportions. Properties like viscosity; calorific value (CV); pour point (PP); cetane number; could point (CP); flash point and fire point are measured for each blending ratios, and it is examined against the relevant standards (USA ASTM D 6751; Europe EN:14214 as well as India IS:15607). Plot between the properties and different blending ratios is drawn, and regression equations (R2) are formulated from which biodiesel properties are predicted and compared by mineral diesel. From this investigation, the optimal blending ratio is projected considering the different properties of biodiesel.
